These are all the "folio" type design though, not sure if thats something you are interested in.
The Poetic Slimbook, it's pretty good.
OP, how far does the case encroach on the (side) bezel? For example, does it affect a tab-changing gesture in Chrome?
You might want to take a look at the Poetic Slimbook, might suit what you need - Acts as a wallet, and it's actually cut specifically for the N4 so the camera and speaker are exposed, as opposed to generic cases - Only thing is you may not like the "flip open" aspect of it, since it covers the front, unlike the case you mentioned. It's magnetic, not snaps, though, if that matters. Be aware you can usually find them on Amazon for cheaper than the official website is asking.
Their other cases are pretty good too, their Borderline bumper case has kind of been the go-to around here whenever the official bumper is sold out.
